ISO 10924-4:2015规定了用于道路车辆的CB15型带凸耳（叶片型）的中型断路器。它为这种断路器形式确定了额定电流、试验程序、性能要求和尺寸。 ISO 10924-4:2015旨在与ISO 10924-1和ISO 10924-2结合使用。其条款的编号与ISO 10924-1的编号一致，其要求适用，除非根据ISO 10924本部分的特殊要求进行修改。 ISO 10924-4:2015适用于额定电压为14 V直流或28 V直流或58 V直流，额定电流不大于40 a，分断能力为2000 a的断路器，用于标称电压为12 V直流的道路车辆。 c、 或24伏直流或48伏直流。 断路器的尺寸和功能各不相同，例如电气复位、自动复位、手动复位和可切换。 注:根据ISO 8820？3，这种类型的断路器拟用于中等熔断器连接等应用中。虽然标签尺寸和当前额定值可能相同，但性能可能存在差异，建议这些产品的用户考虑到这一点。

ISO 10924-4:2015 specifies medium circuit breakers with tabs (Blade type), Form CB15, for use in road vehicles. It establishes, for this circuit breaker form, the rated current, test procedures, performance requirements and dimensions. ISO 10924-4:2015 is intended to be used in conjunction with ISO 10924？1 and with ISO 10924？2. The numbering of its clauses corresponds to that of ISO 10924？1, whose requirements are applicable, except where modified by requirements particular to this part of ISO 10924. ISO 10924-4:2015 is applicable to circuit breakers with a rated voltage of 14 V d.c. or 28 V d.c. or 58 V d.c., a current rating of no greater than 40 A and a breaking capacity of 2 000 A, intended for use in road vehicles with a nominal voltage of 12 V d.c. or 24 V d.c. or 48 V d.c. Circuit breakers differ in terms of dimensions and functions, e.g. electrically reset, automatic reset, manual reset and switchable. NOTE This type of circuit breaker is intended to be used in applications such as medium fuse-links in accordance with ISO 8820？3. While the tab dimensions and current ratings can be the same, there might be differences in performance, which it is advisable that the user of these products take into consideration.
